curious / hopefully quick question: Is it possible to combine flows into a "master flow"? Or several tasks into a "master task"? Asking here because I looked at examples, didn't see anything obvious, so figured I might be getting into anti-pattern territory. My use case is: • I have several scripts that can run independently. Each define a

Flow

and a

___main___

that calls

flow.run()

. • These scripts need to get orchestrated. I figured I'd make a master flow that knows how to execute the smaller flows and get that master flow scheduled.

Hey @wilsojb, historically we HAVE considered this an anti-pattern, informed greatly by the negative experience of working with SubDAGs in Airflow (I believe it reached such a point that they are being removed in Airflow 2.0). While you can absolutely have a Prefect flow run another flow (it’s just a function, after all), it introduces complexity around nested behaviors that we generally discourage. With that said, over the past few months we’ve collected a number of use cases from the community that we think motivate a clean way to support “sub flows” and “flow-to-flow dependencies”. We’ve created a roadmap item to present a solid first-class way to handle it, but it is not our highest priority at this time.

makes sense. Thanks @Jeremiah! My team and I really appreciate the guidance!
